What this site is, and what it is not
Terrazzo is a method, not a mineral. The same word covers a 4 mm resin floor and a 30 mm pressed panel, and most of what is written about it treats those as one material. This site is about the differences.
Everything published here answers one question first — <strong>which process is this about</strong> — and then gives a figure or says plainly that no figure is available. Where a number comes from a standard, the clause is named. Where it does not, the page says so.
Sourcing
Blocks are bought at the mine rather than from a trading desk, so the origin of a slab is a fact we can state instead of a promise we have to hedge.
Processing
Cut and finished in Shuitou and Yunfu against the batch, not against a photograph of a batch from another year.
Answering
A question with no published answer is written as having no published answer. That is more useful to a buyer than a confident number that turns out to be wrong.
What is published on this site
Six processes, drawn to one scale. The thickness bands a system occupies. The chip sizes each thickness permits. The four grades of absorption and strength, and what each one is for.
| Question | Answer |
| What are the six types? | Six processes with their layer stacks |
| How thick can it be? | The bands, and what decides each one |
| How big can a chip be? | The relation between thickness and aggregate |
| What does it cost to maintain? | Sealing, cleaning and what each affects |
| Which standard applies? | The Chinese codes, and what the European codes say instead |
What is deliberately not published
A figure nobody can trace to a document is not useful to somebody specifying a floor, and it is the easiest thing for a supplier to invent. So these are absent, and their absence is the point:
Laboratory reports for our own batches
None are published, because we hold none. A composition analysis of one sample is not a test programme: a range needs more than one thing tested, and the twelve physical properties on the specification sheet still read not tested for exactly this reason.
Lead times
They move with the batch and the port. Ask, and the answer given is the one that applies to your order.
Prices
A price on a web page goes stale within a month and is quoted back as current within a week.
What a laboratory measured, and what that is worth
One composition analysis is published here, carried out by SGS-CSTC Standards Technical Services in Xiamen on a single sample: report XMIN2609002523CM01_EN, issued 13 October 2026. The sample reads as mostly calcium carbonate with silicate, magnesium carbonate and sulfate, contains no resin, and measures 0.34% crystalline silica. The sample is not one of the colourways published on this site, and it was supplied by the client, which the laboratory expressly declines to verify. So it is published as a measured composition for a named sample with its report number beside it, and not as a range or as a specification of anything we sell. The full sheet is on the download page, and the report itself is sent on request.
| Component | Content, Wt% |
| Calcium carbonate | 84 |
| Silicate | 11 |
| Magnesium carbonate | 5 |
| Sulfate | 4 |
